摘要
Abstract
An extended sliding-mode observer of the load torque was proposed,of which the state variables were speed and load torque,in order to decrease influence of varying load torque in a permanent magnet synchronous motor（PMSM） control system.Errors between the real and the observed speed were selected as a sliding-mode hyper plane,and the observed load torque was composed of a real load torque and the filtered chattering signal.The observation error converged to zero when sliding mode occurred.A sliding-mode variable structure control（SMC）.system of PMSM was designed based on the exponent reaching law,in which the observed load torque was used for feed-forward compensation.Experimental results show that the novel sliding-mode observer can estimate the load torque precisely,and the designed controller can enhance system robustness and suppress the intrinsic chattering of SMC.关键词
